Abstract
Known protocols for supporting mobility in relation to Internet Protocol (IP) networks are not able to efficiently support distribution of Binding Update messages to Correspondent Nodes () in a set of fixed IP networks (). Consequently, the present invention makes use of a multi-cast service provided by the IPv6 protocol in order to deliver Binding Update messages to the Correspondent Nodes (). The use of the multi-cast service to deliver Binding Update messages avoids a proliferation of such messages which would occur under know protocols requiring a mobile node () to send the Binding Update message to each Correspondent Node (). Consequently, use of bandwith in the set of fixed IP networks () is more efficient.
